Current Trends in the Use of Shoulder Arthroplasty in the United States.

Reverse total shoulder arthroplasty (rTSA) has become increasingly popular since its introduction to the United States. The purpose of this study was to assess the current trends and use of rTSA, anatomic total shoulder arthroplasty (aTSA), and hemiarthroplasty (HA) from 2011 to 2014. Shoulder arthroplasty data from the National (Nationwide) Inpatient Sample database were analyzed for the years 2011 to 2014 using International Classification of Diseases, Ninth Revision, Clinical Modification procedure codes.

The Cost of Joint Replacement: Comparing Two Approaches to Evaluating Costs of Total Hip and Knee Arthroplasty.

Background: In an era of mandatory bundled payments for total joint replacement, accurate analysis of the cost of procedures is essential for orthopaedic surgeons and their institutions to maintain viable practices. The purpose of this study was to compare traditional accounting and time-driven activity-based costing (TDABC) methods for estimating the total costs of total hip and knee arthroplasty care cycles.

Methods: We calculated the overall costs of elective primary total hip and total knee replacement care cycles at our academic medical center using traditional and TDABC accounting methods.
